ATC 200s cam upgrade?

[squirrel1182]

Is there any cheap bolt in cam for a 200s? My buddie has one and he wants more power to haul his fat @ss. Does the xr 200 cam bolt in? or 200x cam? :wondering

There is a slightly more powerful cam on ebay for the 200's. http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=230488725910&ssPageName=STRK:MEWAX:IT#ht_500wt_1182

The xr200 cam bolts right in and can be had for cheap. I got my xr200 cam for $15 shipped. If you are going for true budget go that route. A xr200 cam with no other upgrades will move your powerband to the right more than any other real benefit. This will give you a feeling of a more "awake" setup as it approaches top end it wont go limp as much as it used to. But if you team it with a hi-flo filter, exhuast (DG RCM or something similar), 10.25 piston, and properly jetted carb, you'll have a quick little auto 200.

Worth the $15? You betcha! HUGE difference? Meh, not really. What is your buddies budget?
$15: Cam
$60: Cam, 200x Carb, Filter
$175: Cam, Carb, Filter, Exhaust (at this point I'd personally stop, unless he REALLY loves his hardtail)
$350: Cam, Carb, Filter, Exhaust, 10.25 Piston, top end gaskets, minor porting of head (now he's faster than a 200x, unless there are bumps.. ) : )

i forgot to add that he has a cobra exhaust on it. His budgets cheap. lol. he has too many "projects" going on. (79 cj7, 66 f350, atc 200m, atc 200, 1974 gmc 7500) Im the one that wants to get more performance out of his trike since when mines down i barrow it alot.
